Answer:

x = 30

Step-by-step explanation:

m<A = 60°

m<D = 60°

...

ΔABC = ΔDEF

Therefore, ΔA and ΔD are equal.

...

m<A = x + 30

m<D = 2x

...

Think to yourself, "What can I multiply to 2 that will make it equal when added to 30?"

...

2(30) = 60°

(30) + 30 = 60°

...

Solution:

x = 30

Hope this helps!
